Toall whom it may concern: I

'lBe it known that 1, WILLIAM N. Pumas, a citizen of theUnited States, residing in the borough of Brooklyn, in the county of Kings and State of New York, have invented new and \useful Improvements in Sewing-Machines, of which the followingis a specification.

a This invention relates to the class of sewin, is described and illustrated adapted for use in a well known machine ot'the class mentioned wherein a reciprocatlng needle ismoved laterally to and fro, and in which the 'fe'eding mechanism is of the four-motion kind, but, it is desired that it beunderstood that the use of the invention is not limited to this particular type of machine. And it is also desired that it be understood that while the main use for the invention is-in the class of machines mentioned, it is not limited to this class, for it, or a part of it, may be used in machines in' which there is no relative latera-l movement between the needle and the Work.

As is well known, in the operation of lock needle passes a loop of needle thread through the work and presents it to a hook, which latter'seiies it and passes it around a bobbin case carrying a bobbin of thread, the loop of needle thread being thereby caught around theportion'of the bobbin-thread which runs from the bobbin to the work, then the takeup draws up the loop until the bobbin thread .and' the needle thread at the point where the work where the needle previously penetrated it, and a stitch is said to have been made, then after the feed has completed the movement of the work for the location of a succeeding stitch, the needle is again passed" through the stitchjisflmade as before,'and.so on.

from one to another ofthese stitchesare called here n links ofneedle thread, and the portions of the bobbin thread which runs from one to another of these stitches are called links of bobbin thread.

The invention herein disclosed relates to a sewing machine. comprising a laterally vibrating needle, an auxiliary thread "carrying looper, and improved means for operating it to loop its thread around the links of needle thread; means coiiperating with the auXiliary looper to draw a portion of thelin'ks of needle thread around thelooper thread so that sald portions and the looper thread abuts the edge of the fabric; improved means for hemnni'ng the work inicombination with theworking of the auxiliary looperfi means intermediate the needle and. the raw edge of'the material wherebythe edge of the material is covered so that the ends of'its threads are bent and bound 1 down under the links ofneedle thread and underthe-auxih iary thread; a feeding mechanism; the feed dog of which-extends into the needle-slot, and between the reciprocating paths of the needle, aspecial form'of presser foot adapted for use in combination with the fe'ed'dogand the auxiliary looper, and other improvements which will be described in the specification and specifically set forth in the claims.

The beveled gears areofequal size therefore 1t. Wlll be understoodthat the hook driving shaft and the hook shaft. revolve in unison. To

"the rear end-ofthe' hook shaft issecured a hook'13, provid e'djwith a bobbin case 14-,

which carries a bobbin of threadiiu a usual 'man'nennot shown; A 'projectlon 15 extending from the bobbin cas'eholder and a stop fing'er 16 serve in a usual manner to restrain the bobbin case from rotating (Figs. 3'and 8).

.On a bearing 17 (see Fig. 3) is pivoted a needle bar'frame 18 ,in which is-mounted to'reciprocate' a needle bar l9, which carries odification "of? the special "feed dog i ond-need'le'plate. Fig. 1s a diagram 'may he moved'toward or from the center of the shaft '26,. and suitable means (not shown) intermediate the eccentric and a thumb nut 29 serves to ad ust the eccentric. This means is constructed so the eccentric may be adjusted outwardly from a position where its axis is concentric with the axis of the shaft 26, or vice versa, so it will be understood that usual means are in the machine for adjusting the means for moving the needle laterally out of action When the needle Will reciprocate vertically only as in a plain stitch machine.

The gear 25 is twice the size of the gear 24, therefore it will be understood that the eccentric which operates the pitman 27 revolves once to two revolutions of the driving shaft of the machine' When it is desired to have the needle moved laterally the eccentrio, by means of the thumb nut 29, is adjusted to give the desired extent of movement to the pitman 27. As is usual in these machines during one half of a turn of the eccentric, and just as it has moved the needle bar substantially to one of its lateral positions, the needle enters the Work, loop cngagement takes place, and a stitch is made, then when the eccentric is in the same position in the other half of its rotary movement the needle again enters the work in its other lateral position and another stitch is made and so on. Intermediate the entering of the needle in the Work, the feedingmechanism moves the Work to the desired position for the location of the succeeding stitch.

On the rear end of the, shaft 26 is secured by means of screws 30 a cap 31, in the outer Wall of which. is formed a ,Way 32 that eX- tends from over the center 33 of the cap to its The axis of the can is concentric with the axis of the shaft. This cap serves the function of a collar for the shaft to re tain it in its position longitudinally, and also as a means for transmitting movement to a pitinan 34, the end 35 of which is secured by means of a thumb nut 36, in the Way 32. It will be observedthat when the end 35 of the pitlnan is adjusted over the center 33 ofthe cap, no movement is transmitted to the pitman, and consequently no movement is transmitted to the mechanism operated by the pitman. 4

' ;The forward end 37 of the pitman is suitably pivoted on a ball end 38, of an arm 39, which latter is secured at its other end hy 1 6 1 3 1 P h Screw 40, a looper rod 41. In Suitable bearingsinthe forward end of the of the machine is mounted a, tubular presser bar 42. In the upper end of the bar is a bore 43, that extends to 44, and from this point. to thelower end ofthebar is abore 45 that is smaller than the bore '44, as shown in Fig. 9. Abutting the end 44 of the'bore 43 is a bushing 46, in which the upper end of the rod 41, is journaled, and in the lower endof thebore45 is a bushing 47 in which is journaled the lower end of said rod.

"Througha slot 48 in one side of the presser bar, passes the arm .39, which is flattened on its upper and lower sides at the point where it is in the slot so that it just fits the slot and thereby the rod isheld from longitudinal movement. The slot is of sufiicient length to allow the arm 39 to be moved laterally the desired distance. To the outside of the presser bar is clamped, by means of a screw 49aanarm 49. This arm extends into a slot 49" in a part 497 and thereby prevents the bar from turning, and at the same time permits it to be lifted and lowered in the-usual manner.

Loosely mounted on the outside of the bar is a sleeve 50, provided with an arm 51. An end 52 of the sleeve abuts the arm 49, and a usual pivoted presser foot lifter lever 53 (see Fig. 3) is located under the arm 51, and serves as means for manually lifting the -bar. In the bore 43 of the bar is located a presser bar spring 54, which at its lower end impinges against the bushing 46, and at its upper end against an adjustable bearing 55,

which is located in a-threaded bore in the arm of the machine.

In the operation of lifting the presser foot the lever 53 is turned on its pivot upwardly, when the usual cam portion 53' of the lever engages the arm 51, and the sleeve is thereby lifted upwardly, and through its contact with the arm 49 the presser bar and mechanism carried by it are lifted upwardly against the action of the spring 54 as will be understood from Figs. 3 and 9. And of course a reverse movement of the lever 53 permits the spring to press the presser bar downwardly, until the presser foot, which will presently be described, engages the work. The extent of the pressure ofthe foot on the work is regulated by the adjustable bearing 55.

To the lower end of the presser bar is secured by means of -clamping screw 56 a presser foot carrier 57, to which is secured by means of screw 58, the shank 59 of the special presser foot 60, provided with an open end needle slot 61, nearly across which projects a tongue 61. -In a groove formed in the upper'side of the presser foot, is adjustably secured by withiupwardly extending end 64, in which means of a screw 62, anauxiliary looper thread guide 63, provided is formed a thread eye 65. It will be observed that this construction permits of the lateral ad ustment of the guide, and/also permits of its being reversed so that the end 64 may belocated on the opposite sideof the presser foot to that in which it is shown in Fig. 13. v i i To the lower end of the looper rod 41, is

secured by means of clamping screw 66"(see Fig. 10) a'looper carrier 67. In a way 68, is adjustably secured by means of a screw 69, a shank 70 of an auxiliary. looper 71, the shank of thelooper being provided with a slot 72 through which passes the screw 69 into a seat in the carrier. The auxiliary looper is provided with a nose 73, through which passes a thread eye 74. The slot 72,

it will be noticed permits of the adjustment lifted, and'there is then a free passage under the foot from any direction.

In the preferred form ofmy invention a usual form of feed dog carrier 79, carries a feed dog 80, which has upwardly extending toothed work engaging portions 81 and 82, between which there is a thread passage space 83. A. needle plate 84 is provided with a feed dog slot 85, a needle slot 86, anda feed dog slot 87, one end of slot 87 opens into the needle slot as shown in Figs. 11 and 12. This feed dog, through the movements of the carrier 7 9 and the mechanism which operates the carrier, (not shown) is given the usual well known four motion feeding movement. Under this'mo-vement the work engaging portions 81 and 82'of the feed dog are moved upwardly through the slots 85 and 87 into engagement with the work, then it is moved forward and this moves the work one step in its feeding movement,then the dog is moved downwardly out of engagement with the work, then backward and upwardly again into engagement with the I have incorporated my invention the feeding mechanism has the usual means for increasing or decreasing the extent of the forward and backward movement of the feed dog, and thereby increasing. or decreasing the length of the stitch as'it is usually called, but, the distancebetween the stitches as the stitching is herein defined. ,1

e 8 nd Special Presser foot 60 are cured'in place in the machine as illustrated Figs. 1, 3 and 10, butwith the hemmer omitted. 'lhefextent of the lateral movement of the needle is adjusted so that it moves the needle laterallyja sufficient extent to cross the toothed portion 81 of the feed dog, and alternately reciprocated on each sideof the same. ,The extent of the steps of the feeding movement desired isadjusted by a thumb nut 114, which in a usual man- 'ner (not shown) connects withfnieans for regulating the feeding movement of the feed dog, as before noted. r

In threading the .machine the needle thread 115 is passed from the supply through an eye 116 in'a pin 117 projecting upwardly from the arm of the machine. From thence itis'passed through a guide the face plate 3, then back' and under'a'pin 125, thence between tension disks'126 (only one of which is sly-awn.) and from'there back The auxiliary thread 123 passes from the supply to an eye 124: '11'1 spring (not shown). From this spring the auxlliary thread runs to the eye'65; of

. thread guide 63, and from-the e it g through; the eye-74' of thenose 173 ofthe V auxiliary looper.

' The auxiliary looper 71 moved inthesame direction the needle ig m' d laterally, but always a greaterpex'tent than the needle;- llor. example when thev'needle :Is moved tofthe right,ithelooper is moved, so its nose" if? ,1 is..-to :.the right of the needleas it, the needle, descends tothe' work, and the nosedextends sufiiciently back of the needleto carry ztheauxiliary thread running from previous stitch back of the needle, and when-the needle is moved tothe left -the said loo'per is moved to thc'left so its nose-is to thecleft relative tothe needle in the same manner. The result is the auxiliary thread runs back under each link of needlethread and forward over the topof the same as will be understood from dia grammatic Fig.1(l.

' It will behuoticed that reciprocating path of the needle. This serves to cause the looper thread to be slack; when the looggier 'ruovestoits position to the left, andto be taut and todraw the supply of looper thread when it moves to the light... This movement to the right is against the action of thespring 128, and this together withthe location of the thread so that the take-up begins to give thread just previous to the auitiliary thread cominencing to draw it, the needle tln'ead to one side, causes the needle thread to belooped around the .looper thread at the edge of the stitching illustrated in diagrammatic Fig. 17. When this stitching is done along,

the edge of apiece of fabric so that the needle in one of its reciprocating movements passes to loop engagement outside of said edge the needle thread is drawn around the .looper thread'as illustrated in Fig. 17, and

when so drawn the looper thread abuts the raw edge of the fabric and thereby gives a smooth and very desirable finish to the same.

The bobbin thread is an element in perform ing this functlon, as the usual tension on it draws on the needle thread and thereby as sists in drawing the looper thread the tie sired position.

The bent ends of the thread, as the feed of the work progresses, are held down by the presser foot, and are held against the edge' of the fabric by the separator tongue 94, and, the needle thread from the stitches made when the needle entersthe needle rec'ess 95 together with the looper thread bind these ends of the fabric thread tothe edge of the fabric, thereby giving a very firm and desirable finish to said edge.

When it is desirable to do hemmingga hemmer may be attached to the presser foot as shown in Fig. 10, and the guide may also be used for the edge of the work to abut against, thereby assisting in guiding it and holding it from having a tendency to be pulled to the right from the action of the auxiliary .looper/thread in. setting the stitch, and also serving as a means for assisting in the setting of the stitch with the auxiliary thread along the edge of the hem. 'When a hemmer is used the auxiliary' thread abuts along the outer edge of the hem, and thereby makes a very desirtion as shown in dotted lines in Fig. 13.

able finish. This auxiliary thread may be any-kind of thread or cord in any color, 7

which further adds variety and scope to the finished effect.

I Thefunction of the abutting part 95 ofthe guide 88 is to serve as'an abutment for the auxiliary thread to abut against, and

thereby prevent it frompinching the needle thread when the stitch is being set. This will be understood by referring to Fig. 15, and

'noting that when the stitch is being set the auxiliary thread is pulled to the right so it abuts the "abutment 95,. and thereby permits the needle thread to pass back of the looper thread without being pinched between it and the guide.

When it is desired to hem the edge offla piece of fabric, and at the same time sew a piece of lace or other material along the edge, the guide 88'is removed, the part may be reversed so it is in an opposite posi- This puts the finish along the edge of the left of the stitched path where-it is very desirable in this kind of work; Now the lace is'guided along the edge of the presser'foot at the right, and as the needle reciprbcates -'ust outside of this edge the lace is connected Eat it substantially abuts said edge' When .it is desired to do general plain or ornamental stitching, .or broad hemming, or hemming with-the hemmer; attached td the bed of the machine...

the d? 0%, i ed plate, and presser foot, illustrated in Figs. 4, 5 and 6 are used. In the presser foot shown in Fig. 6, abutting parts 100 and 101 together with recesses 98 and .99. serve to prevent the looper thread from pinching. the

. needle thread, in substantially the same manner as has been described in connectionwith the guide 88. The feed dog work, engaging. part 81 is moved to the position shown. in

Fig. 12 in moving the work .forward,in

which position it will be observed that the toothed portion is past the reciprocating pathof the needle. Of course the position of this feed dog relative tothe reciprocating 4 path of the needle, in thefinishing of a feeding movement, is changed when the. ex-

tent of feeding movement. of the dog is.

changed. This construction and location of the feed dog is very advantageous in various.

feeding it forward, thusit will be understood that the construction of the feed dog so it operates in the same manner described serves as a means for the feed dog engaging,

the work at the extreme edge of the corner just where it is desirable. to commence the stitching. This is advantageous in anykind of work where it is desirable to commence the stitching at the extremeedge or corner. When the general presser foot 96 is used, a filling cord or material may be run from the supply to the eye 129, from thence to guide 130, and. then through theeye in the tube 104 which guides it under the lateral.-

path of the needle- Of course a tube may be inserted, or any other suitable means may be provided to run a filling material under. the lateral path of the needle, when the" special presser foot, or any otherfpres'ser foot is being used. If it is desired to use two needles and to produce the stitching illustrated in Figs. 22 and 23 the two needles may be carried by the needle bar in any -usual manner for exampleinthe manner illustrated in Fig. 2.4. TheseJneedles are located abreast, at right angles to the direction of the feed. In said Figs. 22 and 23 the needle 131 represents the additional needle, 132 its thread, and 115 the needle thread of needle 20. In using these": two

needles the usual adjustment is made by means of thumb nut. 29,.to'discontinue the lateral movement. of the needle bar, so that both needles reciprocate. vertically without later-a1 motion. Thetwo 'needlesare, separated a suflicientextentso that cine-reciprocates on one-side of theportion 81 of the feed dog, and the tongue 61, and the other nee ille on the other side of the said feed dog portion and tongue.

' In the operation of the. machine with two needles in it, the auxiliary looper is operated in the same manner as has been described in connectlon with the use of one needle.

The needles are passed through the work, the hook. seizes the loop of the needle threads of both needles and passes them around the single bobbin in the usual way. The auxiliary looper thread, to make the stitches illustrated in Fig. 23, is threaded through the eye 65 of the thread guide 63. This causes said thread to'be taut whenthe auxiliary looper moves to the right at which time the supply of auxiliary looper thread is drawn, and to be slack when the looper is moved to the left when no auxiliary looper thread is drawn. From this action the needle thread from the needle at the left and'also the auxiliary looper thread are drawn to the right, and to the edge of the fabric, or

\ stitched path'as illustrated in Fig. 23. In

making tliese stitches the bobbin thread will connect the stitches on the under side of the fabric as illustrated Fig. 23'.

In the use of the preferred form of'presser in dotted lines in foothill the tongue 61 serves, in addition to its other functions, to take the strain of the lateral stitches, thereby permitting of a suitable tension being on the thread to set the stitches without puckering the work.

In the preferred form of my invention,-

' in which form the vauxiliary looper' draws its thread and the needle thread with which it concatenated. to the edge; of the stitched path, or to the edge of the fabric when it is desired to cover such edge, the loop er. is consti-ucted and operated so it finishesv its stitch setting movement after the take-up has finished its stitch setting movement asbeforenoted. The finishing of the stitchsetting movement of the take-up is at the time when the take-up has reached its highest position, which isjsubstantially the position shown in dotted outline in Fig. 3, and the finishing of the stitch setting movement of the auxiliary looper is, when the stitch is being set on the right of the stitched path for example, substantially in the position shown in dottedoutline in Fig. 11. By this con'struction and operation the -auxiliary thread and the l nks of needle thread are firmly looped and set abutting'the edge of the'fabric, or

when stitching is on the interior of the work, along the edge of the stitched path.

- The workvof the character'doneby the invention herein illustrated, is very advantageous-for use in finishing the edgeloredges of stripsof material. To the endthat this? mayvh e done at I have 'ing this work automatic:

provided means for guiding such strips of assistance from the operator.

The means for guiding the strips'of work "so the machine will finish, an edge of the same automatically comprises the following:

To the top of the bed 20f the machine (see ,Figs. 18 and 19), is secured by-means of, screws 133, a bracket which is generally ::The spindle and roller-turn very freely on their bearings so it will e understood that the feed dog very readil? carries thezwork along automatically while the machine is finishing the edge. In connection with doy itis noted that while the mechanism is stitching only one "edge .5 the material, it is obvious that by duplicating the means shown a plurality of edges may be simultaneously stitched.

It is noted that with my invention as herein illustrated various work, other than the kind herein mentioned may he done, and also other functions may be performed. It

is also noted that applicant does not wantto be limited to the specific means, or constructionfherein shown, as these may be changed in various ways Without departing from the spirit of the invention. f

It is further noted that certain parts of the invention are not essential to the per formance of the functions of the invention.

For example, the guide 88 is not essential ito the weaving of the auxiliary thread with the needle thread along the edge of the work. The guide however serves to assist in guiding the work so that the stitchingwill be uniformly along the edge, and positioned so that the auxiliary thread will be more certainly located along the edge.
